Gidday mate,

Looks like you're trying to compare a value of null with the value of a string. I'm just assuming here, but I would say your data type needs to be changed from a string or text, to a number or integer value

I want to add a query to filter a column called "update" and return values when it contain the value "2"

Can you help ?

Try get all items without a filter query, then use the filter array action after you get items
